The refrigeration system of the air-cooled condenser requires regular cleaning of the cooling fins to remove dust and dirt. One with a nozzle brush can be used, being careful not to damage or bend the fins. Cavities and shelf surfaces must be kept clean. It must be cleaned after each run to ensure that spilled product, corks and broken glass are removed. Use extreme care with thermocouple wires and jacks. A preventative maintenance program helps ensure that all scheduled maintenance items are carried out according to the recommended schedule, which will help keep your freez ... Read More

After the freeze-dried product is vacuum freeze-dried in the freeze dryer, the product needs to be taken out of the box and sealed for storage. Since the freeze dryer is still in a vacuum state when it is finished drying, the product must be put in air before opening the warehouse door to take out the product. The air put in should be sterile dry air. Due to the different storage requirements of the product, the handling of the freeze-dried product out of the warehouse also varies. Some products only need to be placed in sterile dry air and sealed out of the box for storage ... Read More

1. The automatic packaging and cartoning machine reduces labor costs and maintains speed, precision and stability. 2. Improve labor productivity, the speed of automatic cartoning machine is much faster than manual packaging. 3. If manual packaging works for a long time, mistakes will inevitably occur, resulting in unnecessary losses, but using a packaging machine can be greatly avoided. Although the automatic packaging machine is not 100% error-free, the error rate is very low. 4. The automatic packaging and cartoning machine can pack things that are not realized by hand or ...

The cartoning machine is a machine with very good performance and quality. Irregular use and lack of timely maintenance are the reasons why the cartoning machine cannot work normally. If you want to be able to run the cartoning machine stably for a long time, it is mainly necessary to strengthen its maintenance. When using this cartoning machine, the work efficiency is often not high due to improper operation. Today, I will introduce to you how to use the cartoning machine. 1. Before using it, you must do the relevant preparations first. Check that all safety devices are pr ... Read More

During the use of the vertical cartoning machine, the machine cannot work normally due to the wear, deformation, corrosion or even improper operation of the parts. The reason is basically the change in the relative position and working relationship of the parts of the automatic cartoning machine , causing the technical state of each part to be unable to operate normally, making the working ability of the cartoning machine decrease or even lose. Common faults are generally difficult to start the engine, increased fuel consumption, decreased power or other abnormal phenomena, ... Read More

(1) The speed of the machine is limited by the speed of the lower instruction manual and the lowering plate, and the design should be more reasonable; (2) The stability of the machine is relatively poor after long-term high-speed operation, requiring stable operation and more use of servo systems; (3) The accuracy cannot meet the requirements after long-term operation, the synchronization is not good, and the reliability is required to be improved; (4) The adaptability to the product is low, its function is relatively single, the adaptability is relatively narrow, and there ...

1. Pre-freezing speed Most freeze dryers cannot control the pre-freezing speed, so the pre-freezing rate can only be determined by the pre-freezing temperature and the packing time. If the pre-freezing rate is fast, the freeze-drying chamber should be lowered to a low temperature before the product is put into the box; if the pre-freezing rate is slow, the product should be cooled down after entering the box. 2. The minimum temperature for pre-freezing This temperature depends on the eutectic temperature of the product, and the minimum pre-freezing temperature should be low ... Read More

During the freeze-drying process, the pressure in the freeze-drying chamber used to be thought that the lower the better, but the current view does not think so, but should be controlled within a certain range. The low pressure is of course favorable for the sublimation of the ice in the product. However, when the pressure is too low, it is unfavorable for heat transfer, the product is not easy to obtain heat, and the sublimation rate is reduced instead. Experiments show that: when the pressure of the freeze-drying chamber is lower than 0.1 mbar, the convective heat transfe ... Read More

Food vacuum freeze-drying technology is a new type of food processing technology, which is considered to be an ideal dehydrated food processing method and can be applied to the drying treatment of many fresh fruits and vegetables that are difficult to preserve. In recent years, the emergence of freeze-dried apricots has also verified the feasibility of freeze-drying technology in the food processing industry. Apricot is rich in nutrients and contains more sugar, protein and minerals such as calcium and phosphorus. Apricot fruit has the functions of clearing heat and detoxif ... Read More

The freeze dryer dries at low temperature, which will not denature the protein, but can make the microorganisms lose their biological activity. This is especially suitable for dry preservation of biologically active products, biochemical products, genetically engineered products and blood products with poor thermal stability. The freeze dryer changes the tedious operation of the drying process in the past, prevents the pollution of materials, and realizes the automation of drying and sublimation, which is suitable for pilot or mass production. The freeze-dried articles are ... Read More
